So i have an ASUS ROG crosshair V formula Z motherboard, but ive noticed its running at mid 60sC when playing not very taxing games, if i were to play bf4 it would starting hitting 70/70C, way too hot. My case is the FAH 912 plus, so my question is, what is the best way for me to improve my cooling. currently the heatsink is outdated and not very good, so that needs replacing, but id like to go wootercooling (just a little self contained cpu one). so what would fit, whats good, i dont know much about heatsinks or watercooling since ive never had an issue with heating before. the rest of my build is: CPU: amd fx 8x 4.0ghz GPU: sapphire 7970 vapour-x 3gb ram: 8gb. i was looking at the crosshair h100i for watercooling, but im not sure ti would fit. thanks in advance.
